Windshield wiper unit for ships

First produced in 1938, the SPEICH Clear view screen is a high technology product, carefully engineered in all it’s details and designed according to ISO 3904. Many decades of field experience and constant technical improvements have made the SPEICH Clear view screen extremely reliable and durable even under the severe environment conditions. Tens of thousand units have been supplied all over the world and are installed on alI kind of merchant and military ships, yachts and tugboats. Schematically, SPEICH Clear view screen keeps a glass disk free from rain, snow or sea-water by fast rotation. The motor is placed in the center and is fastened to the fixed glass so as to obtain the largest possible field of vision. This particular assembly also makes the unit water and airtight, thus making it suitable for pressurised and air-conditioning bridges. The rotating glass is hardened and opticaly rectified to avoid any optical distortion. The electric motor is available for many tensions; the rotor is tropicalized and turns on silent ball-bearings. All metal parts are made of brass; a specially designed manifold between the ring surrounding the rotating glass and the fixed frame keeps water from entering the space between the fixed and rotating glass. This space can optionally be heated by electric resistance to avoid condensation and ice formation, which could prevent proper operation counter-ring.
